Army chief General V K Singh today handed over to the CBI his much talked about complaint along with some documents on the alleged bribery offer made to him by a retired army officer to clear the supply of a tranche of sub-standard vehicles to the force.

Sources in the CBI said agency is seeking legal opinion from the Attorney General on the contents of the complaint and a decision on further action would be taken tomorrow after his comments are received.

A preliminary enquiry or an FIR could be registered after completion of the procedural requirements, the sources said.

The CBI officials were tight-lipped about the contents of the complaint terming them as "highly sensitive and confidential" which could not be made public.

They said Gen Singh has mentioned in the complaint that he has brought the matter to the knowledge of his "seniors" when the incident took place.

The Army Chief had claimed in media interviews that an equipment lobbyist had offered him a bribe of Rs 14 crore, a matter he had reported to the Defence Minister.

The ministry had then recommended a CBI probe into the allegation made by the Army chief.

Later in the initial communication to the CBI, the Army chief had said that there was a bribe offer from retired Lt Gen Tejinder Singh following which the CBI had asked him to submit detailed description of the incident, list of possible witnesses and supporting documents on the issue.

After 10 days, Singh today sent the complaint to the CBI in which he has given detailed description of the incident during which he was allegedly offered bribe, they said.

Tejinder Singh had refuted the allegations levelled by the General and also filed a defamation case against the Army chief and other officers.
